Apple is trying to ban the sale of ten Samsung smartphones and five tablet computers in Germany after filing a lawsuit with the Dusseldorf Regional Court regarding the design of the devices, reports Bloomberg.

The smartphone suit concerns EU-wide design rights for devices that include the Galaxy S Plus and S II smartphones, while the tablet suit is connected to a September ruling that implemented a temporary sales ban on the Galaxy Tab 10.1 in Germany. German news agency dpa has said the cases will go to trial in August and September this year, respectively.

The two companies spent much of 2011 battling each other in courts around the globe about the design and technology of their products. Apple started the legal action in April by accusing Samsung of “slavishly” copying the designs of the iPhone and iPad in its designs for the Galaxy smartphones and tablets. Since then, there have been disputes in Australia, France, Germany, Italy, and Japan.

According to FOSS Patents, Samsung has filed complaints connected to seven technical patents against Apple in Germany, with Apple suing Samsung over six technical patents. Towards the end of last year, Samsung brought additional infringement claims related to four patents, two of which are standards-related. The non-standard-related patents included a method to enter emoticons.

FOSS Patents’ Florian Mueller said in a blog entry that the design disagreements will be harder to resolve than the technical ones as the latter can be solved through cross-licence agreements.

In response to the German ruling banning the sale of Galaxy Tab 10.1 in September, Samsung altered the 10.1’s frame design and moved the location of the speakers to sell it as the Galaxy Tab 10N. The court said in December that it was unlikely to grant an injunction against the revised device.

Apple has also engaged in patent disputes with HTC and Motorola. A US International Trade Commission judge recently ruled that Motorola had not violated any of the Apple patents listed in a lawsuit. However, the same body ruled in December that HTC had violated an Apple patent believed to relate to data-detection technology.
